Node Red MQTT on the Raspberry Pi

- Node Red has quite rightly generated a huge head of steam in the 3 years since IBM released it as an Open Source project. Here I quickly review the interface and short circuit some of the installation and upgrade problems. If you need a reason to learn OO JavaScript then this too is an excellent starting point.
A BETTER UPGRADE IS HERE • Node-Red Raspberry Pi ...

There is something so satisfying about watching a great video presented by a man doing an awesome Jeremy Clarkson impression.
Richard. Absolutely wonderful vid. One of the best, most comprehensive mixture of information i've seen anywhere. Thank you Thank you!!
Thank you Paul - must stop clicking the 'like' icon on my own videos..
Paul Morley Superbly spoken like an act in a Shakespearen play but with a real solid knowleable practiced flow.
Thank you for taking the time to produce such a thorough flawless presentation!
A BETTER UPGRADE IS HERE th-cam.com/video/z9a_ztJqaII/w-d-xo.html
You have a wonderful voice for narration. The content is fabulous too.
Thank you Carole. I appreciate your time responding.
I 100% agree
Probably the best node red video I've seen for beginners! Awesome job, man!
Ah - great to come home, grab a beer, site down and have my ego massaged. Cheers
Extremely well presented! Thank you. Subscribed!
I am truly honoured! I'd love to pop in and visit you when I drive to Prague next time.
No problem! Just announce yourself via Twitter or Facebook and I will tell you, if I can make it.
This was long, but it was engaging enough and the topics interesting enough to keep me here for more than an hour, as I was following you step by step. THANK YOU for this magnificent work. I know this is hard to create. Really appreciate!
It was only when I completed it that I realised how long it was (in fact I removed all of the Python linked material). I appreciate your comments. Thanks.
A really good introduction Richard. Many thanks.
Opps - wrong link - shouldn't really be pressing the 'Like' on my own video - but thanks Dave for your comment and Merry Christmas and a Happy New Year to you too.
WOW, this was an impressive introduction to node-red and mqtt, including a complete description of the installation of node-red and mqtt. Thanks.
Thank you, your comment is appreciated. This is the product of some version mis-alignment issues that I had. Do have a Very Merry Christmas and a Happy New Year.
Really great introduction to Node Red. Very clear and comprehensive video, thank you Richard for a well edited guide with great visuals to help re-inforce concepts. Can't wait to get started. Still waiting for upgrades to complete after 3 hours.
I've started to think that I should have posted an img file - still might some time. Let me know how you get on.
can i just say that this is the best , bar none , tutorial of node red on the interwebs and it is my 'go to' video when i have any sort of issue with the mighty Node Red
Thank you. Do go to the update - a lot has changed since this filming.
@@richard_wenner there is an update ? superb news
@@familyplans3788 should be referenced below the first video. th-cam.com/video/z9a_ztJqaII/w-d-xo.html
I know this is an old video but wanted to thank you for one of the best videos on this subject. While I have a boatload of Raspberry Pi's around the house, mostly for KODI, and lighting display stuff, I had never tried Node Red simply because of, shall we say less than stellar information/videos on the web.
So, yesterday, using your video, I was successful in getting a Pi running Node Red and even sending e-mails which, for anyone who has tried to do send e-mails in a C or VB or other language, knows is not an easy feat. With Node Red, a few click, enter basic account information, deploy, DONE.
Brilliant best describes you ability to convey a subject in a clearly understood manner.
Hope to use this to get off of ewelink's [ITEAD Sonoff] server and use the Pi/Node Red/MQTT to run my home automation.
Thank you very much.
I appreciate this. Thank you.
Thanks Richard for all the effort you've obviously put into this great video. This is only the second time I've commented on a TH-cam presentation and I'm doing it to show my appreciation and express my hope that you continue to share your impressive knowledge and teaching skills.
Much appreciated. Thank you.
Few years already left after that publication, but probably it still is the best, and all-in-one video explaining Node-Red basics. Thank you for your effort.
Thank you!
A better route my be:- th-cam.com/video/z9a_ztJqaII/w-d-xo.html
extremely well done in presenting such complex concepts in easy to follow manner, thank you and pls do continue to post more
Great intro, thank you! I could listen to you forever, can you please record an unabridged read of the Hitchhiker's Guide to the Galaxy? ;)
Wow - two classics that can never be repeated 'Hitchhiker's Guide' (Radio Version) and 'The Prisoner' (ATV 1967)! (Oh and possibly 'Tales from the River Bank' Johnny Morris - in fact anything by Jonny Morris). erg - what have you started here? Thanks for the comment. :) (This is going to be a mind-worm for the rest of the day! -Damn you sir!)
What a great help this has been for me. Eloquently put along with a great voice, I somehow felt very calm with you talking me through it. Ive subscribed and will be watching the whole series. Fantastic that you show so much about updating the Pi too, wonderful work, many thanks
Now look into my eyes and log in. Transfer all of your worldy goods into the following bank account trust me trust my voice ....... sleep sleep press those buttons ......transfer that money ..... Sorry Dean do let me know how you get on.
Holy crap dude! You are one of the best teachers I have ever come across. Thank you so much!
I appreciate this - thanks.
This is one of the best tutorials i came across for understanding node red integration with Rasp pi. BTW i am not a coder still node red makes it much more easy to integrate devices and communicate with each other as well as to the internet.
Yes, Node Red is brilliant! Do have a look at A BETTER UPGRADE IS HERE th-cam.com/video/z9a_ztJqaII/w-d-xo.html
A new favorite channel for me. I can detect when something is well done and I sure that's the case here. Looking forward to learning a lot.
Your comments are appreciated - thank you.
Good tutorial. Had a poke with Node-red just today found it confusing initially but its quickly making more sense.
Going to revisit this video a few times when I have more time to play with the hardware side.
This came on in the background and I thought... what on earth is Jeremy Clarkson doing on a Raspi channel! So i quickly found this tab to see. Its unbelievably canny. wow. Thanks for the vid too.
Life on the internet and serendipity eh? Cheers.
Best tutorial on Pi, node-red and MQTT setup I have ever seen, thanks.
Thanks. Should I have covered how to secure Node Red and MQTT when you expose your Pi to the wider world?
Omg I didn’t know about this, this is awesome! Thank you for making this video!
Well it was some while ago but thank you for your response. Good luck discovering more!
Great stuff Richard, many thanks...was able to work through all the examples with your clear, detailed guidance.
Looking forward to more of your tutorials/info-packs.
Thank George - what are you thinking about doing? I'm playing with IoT.
Outstanding, clear and appreciate you creating and sharing. Love the classic game sound.
Much appreciated. Thank you.
Very impressed with this video, in fact I have shown it to several others. It has given me food for thought of how to proceed with my homebrew custom IoT solution and MQTT
Excellent - keep us posted as to how you get on.
I follow Andreas Spiess videos... i am surprised to see his comments here... Speechless.. Thank Q
I drove out to spend a wonderful day with him and have met again whenever possible. I was really pleased to arrange for him to come and speak at the Reading Things Network event. He is a God With a Swiss Accent as far as I'm concerned.
Thank You. This was an excellent intro into Node-Red. I wish I had watched it before I spent time on my inexplicable errors!
Thanks Gary - there is merit in struggling :) Happy New Year and sorry for the delay in replying.
This is very informative . as a beginner on this subject I now know an end to end perspective- very effective visuals and presentation- thank you sir...
Thank you Ramesh - good luck with your 'playing'.
This was totally 'gold quality'!
Very well done, very good script, very good narrating, very pleasant voice and accent, and by the way, you should do audio-books for a living, if you are not already doing it
:o)
Liked, commented and subscribed.
Constructive feedback: the only thing I would lose would be the repeating audio separator (i.e. 37:22).
Again, five stars for your work.
Thank you very much!
Thank you. I appreciate your comments. Makes it all worthwhile.
Wow, Richard you did a wonderful job explaining everything and making it look super easy. This is much easier to use than Arduino's "Processing" language (even though it's still helpful to know). Thanks!
Ah I did enjoy Processing but my students saw it as a backwater. Thanks for your comments.
In 2018 the best thing so far is to subscribe to you site
i like your clear way of explaining things. Great work Richard , thank U verry much !
Well thank you both - keep me updated with your achievements please.
Richard rocks! Thanks for such a good Node Red RPi tutorial.
Cheers - don't forget this though th-cam.com/video/z9a_ztJqaII/w-d-xo.html
Great video... very clear and still relevant. Thank you!
Quite enjoyed the narration, reminded me quite a lot like the game "The bards tale". At some point I was expecting to be insulted.
Bravo :)
I can do insults - but that's an extra :) Happy New Year and sorry for the delay in replying.
This is extremely well presented, thank you for doing this and sharing!
Thank you
It cannot get any better. Thank you for the wonderful video.
Thanks Vijay
Excellent ! Very well done and incredibly informative. Great jump start for me on my path to IoT mastery from basics. Subscribed & Thank You!
Well thank you for your feedback. Sorry for the delay in replying. How did you get on?
The most exciting software environment.......in the WOOOORLD!
:) and I'm sure there is much more to come and be developed.
Best intro I've ever seen thank you!
Thank you.
Great video with such much useful and exciting information. Thank you!
Thank you.
thank youRichard. These tutorial was really helpful for me as a beginner. Hope you much more tutorials.
It's great being a beginner - so much fun to come!
Best ever MQTT explanation!
Thank you.
Great video. Thank you. I made the mistake of trying to get mosquito running on a fresh install of Stretch. Cost around 3 days of head banging before going back and digging out the latest Jessie and starting again. All now working and talking to an ESP loaded with Sonoff-Tasmota. Problem is that mosquitto is dependent on some libs that have been dropped in Stretch. Some say that getting this lot working and then upgrading to Stretch does work but I have not tried. Mike
Mike This is all part of the fun of Linux .... Open Source ..... you feel f***ed it took so long but GREAT when it works .... thanks for your reply - let's know how you get on
Somewhere I've a video of pure exasperation th-cam.com/video/Y4Nka-jbHCY/w-d-xo.html you can hear my despair - keep going!!!!!
Crisp and clear.. Thank you so much!
Thank you. Have fun.
The voice and the explanation is really wonderful.
and your typing is impressive too!
Your video was the major source of information on Node-Red for my final year Engineering Project. A huge thanks for that !
Well this is really appreciated - thank you for letting me know. All the very best with your career (I'm, of course, assuming everything went well ;) ).
Very clear instruction. Enjoyed the narration too! Thanks
Thank you.
Awesome tutorial. Very useful tutorial. Thank you sir. I have just started working on iot. Hope i will learn lots of things from you.
Thank you. Do have a look at th-cam.com/channels/u7_D0o48KbfhpEohoP7YSQ.htmlvideos He is a joy!
awesome video... well presented and great voice over... first time finding out about node red :) :)
Smile mode on - thanks!
Thank you, really enjoyed the video. Its a fantastic way to learn so professional. I am now going to give it a go
brilliant - it will change and take your life! :)
Excellent article and nice presentation.Thank you!!
Thank you.
Richard, terrific video, really well done!
Thank you John.
Thank you for a great starting point. The many building blocks of the Node Red world are now a bit more understandable.
Richard well made video I enjoyed watching Node-Red
Hi Richard, impressive work!! Little advice from another video maker: split the subjects up in different video's. Give your audiene time to breathe. People nowadays do not have a long attention span. That why they watch video's. Tutorials longer than 10 minutes are to long. Write the command lines in the discription, so they can copy paste. And give something away. For example in this video you install a lot and tell to make a backup of the image. Why not share the image?
Just an advice from somebody who also is learning it the hard way. Have a good Christmas and a healty 2017.
I really appreciate this feedback and particularly from an author with such a track record and excellent comprehensive content. I agree with everything you say but I have to say I am being a little selfish here as I just do not have the patience and thoroughness to package everything in the well structured way that you do. (I also have that short attention span ;) ). I think the items link sequentially.
I've moved slightly away from my normal audience - which is local primary schools to the point where I have now started inserting single pages of intense detail (a little like that days when the BBC used to do a 'data-burst' at the end of computer programs - where you were expected to record them using old VHS Tapes).
Another issue regarding the speed of delivery would be the recent addition of 'playback speed' function to speed up or slow down the speed of delivery.
As for the code - I would provide a link BUT part of the point of this video is that keeping up to date is an almost impossible process. Any code would also be out of date and I want the viewer to build the latest - to get the best performance AND have the sense of achievement / education of following the process and achieving the outcome. Any way I am rambling ....sorry
This is turning out to be a very civil list - so Marry Christmas and A Happy New Year (I home to visit Amsterdam in the coming days to meet the folk at TheThingNetwork). Thanks once again.
Do you know - I'd really like that. I'm driving to Prague over Christmas and hope go via Amsterdam and Zurich - to meet the folk at TheThingsNetwork.org (let me get some details together and I'll contact you). Do you know of TTN?
I want to get to Amsterdam in March/April - are you free then some time?
Because of your style and eloquence of delivery, this could have been 2 hours long and I would still have watched it!!! If something is as well crafted as this, people do watch it.
I have watched this many many times. Probably a dozen times or more, so totally disagree with the above, with respect.
Richard, please keep pumping out your work, you are a life saver and have moved me on along with Andreas Spiess, you guys are my hero's
Many thanks Dean - that 'guy with the Swiss accent' is a hero of mine too!
Amazingly awesome tutorial! Great job done...
Thank you.
Outstanding! This is THE tutorial. Many thanks.
THE thanks from me :)
Sir. You got me inspired… I am setting this up right now. Thank you!
That's pleasing - thank you.
FYI. I successfully completed the setup last night, including Mosquitto. I can access my Pi’s Node-Red from within my Lan without any issues. Thanks to you.
Excellent - now secure both Node Red and Mosquitto - with passwords - and using the secure version of Mosquitto (if you are going to put this on the Internet and also see Peter Scargills work with Node Red
I’ll get to that immediately, thank you.
I needed this for work, thanks alot!
Work? Playing with Pis is pure enjoyment. You have a great job. Thanks for your feedback. It's appreciated.
@@richard_wenner I started working at a real life escape-room company in my town, and we produce our puzzles by ourselves, including the usage of node red, so this was very helpful to me. :)
Very nicely done. Many thanks.
Thank you.
Stanley is that you? awesome voice
24:12 creepy, are you a robot?
mqtt is great at very long distances I tested this out myself, first there's a long response but preceeding responses are in real time
Just THANKS i now have a clew, before i had no idea!
That's good! Makes it worthwhile.
thanks this exactly what i was looking for. liked
Thank you
This is great. Thank you
Absolutely brilliant video.
Actually got it working on Pi Zero whilst watching the video and all through SSH.
I would love to know how to make an android app as simple as node red that is also connected to MQTT
Try appinventor.mit.edu/
Very well presented. Loved it!!
Thank you
Superb description!
Thank you, Peter.
Very good and useful presentation Thanks
Thank you.
This is fantastic. Thank you. Out of all the options for flash & communication between the ESP8266 & the Raspberry Pi, this won me over to Node Red.
One question: What browser are yo running on the Pi? It doesn't look like the default.
I *think* that was then new Chrome option - I tried to make this an installation from default and I feel sure this replaced Iceweal by then. Have fun!
Awesome, thank you for this great introduction ;-)
Ta, let me know when you have conquered the world!
World succesfully conquered, openhab is no longer needed, i can see now all my data via dashboard on my iphone :-)
I't good to take direct control.
I'd swear you could do voice overs for Jeremy Clarkson. Well, the Stig did this in 2 minutes flat. Your time was.....
Not entirely sure how to take this :)
@@richard_wenner The first thing I thought when the video started was: Jeremy Clarkson's doing a voice over. Add a touch of sarcasm and I swear no one would know the difference.
Subscribed. Quality stuff.
Thank you.
awesome video...
keep going...
Superb video! Thanks:D
Well thank you.
Good work . thank u
Thank you.
thanks Richard great video!
Thank you Gert.
Richard, Thanks for the informative video. I followed the video and set up a pi then played around with node-red and the dashboard ok. I am wanting to know how users can be limited to only accessing the dashboard(application) but not the node-red flow design screen? Thanks
My immediate response is to use simple PHP password page protection - although this does get away from the 'no need to know any programming model'.
Phew I am just going to pick my brain off the floor
Have you recovered?
I’m grateful to see such an elaboration. Hats off to your knowledge and presentation skill. Undoubtedly I’m newbie into this, and exploring all I can, may be you could point me to the right place, if there’s a guide to get expertise over nodered. I’m still unable to correlate some basic stuff sometimes...my first project I’ve decided is to have complete dashboard for my room lighting controls. I’ve already bought one Nodemcu.v9 and got raspberry pi able to use gpio pins. But not over wireless MQTT.....please advise me. Thanks in advance.
Mandeep - thanks for you comments. Don't worry about being a 'newbie' - it's more exciting when ehter is so much to learn but frustrating if you don't have friendly support at hand. I've not found a single source on Node Red - but doo search their site for a growing array of information as this area just exploads. Peter Scargill is also a regular and brilliant advocate. Master MQTT there is not a great deal to it. I keep meaning to do a piece on securing MQTT as a single central access point into/out of the home - it's just time! Good luck (If you have not discovered Andreas Spiess you are in for a delight too! :)
Richard, I really appreciate your reply. I’m now feeling better as I couldn’t find any 300 pages pdf which could’ve given me more peace.
Please answer my one and only question, using raspbian/nodered 192.168.1.5 how to send mqtt message to the “Nodemcu” 192.168.1.4 listening on mqtt (on same Wi-Fi) another ip in my lan.
@@mandeepmails First question is can you ping between these devices? If so set up MQTT on the Pi. The bit I cant help with is setting up MQTT on Nodemcu that you would needd to hunt for but get back if you have not done this by next week (I'm busy writing an article at present so can't go further). With Node Red it helps if know a little JS. here is a link to some good and very cheap on line courses. www.eduonix.com
@@richard_wenner Yes i can ping 192.168.1.4 node-mcu-relay using ping-node/java-bean from node-red 192.168.1.5 (running over raspbian)
@@mandeepmails Well surely you are almost there? Run the MQTT server on your Pi and then Point Node Red at it. You can run a terminal to ensure that the ports are open (from anywhere at a baisc level - as the video shows. The final thing (I've not tried it) is to try to run something like Mosquitto on your Node MCU www.instructables.com/id/NodeMCU-MQTT-Basic-Example/
Hi,
Nice video, thanks ! I have two questions :
1. How to run node-red in the background ?
I tried "node-red &". It runs in the background but repeatedly surfaces in the foreground.
2. How do we start node-red automatically in the background as the pi boots up ?
So, we do not have to ssh every time and type in "node-red".
I tried adding "node-red &" in /etc/rc.local. This does not work i.e. it does not even start node-red.
Please let know.
Are you using the Pi in text or GUI mode?
Thanks Tom
10:10 "Pushbutton to pin 13" Isn't there a short circuit if the pin is defined as output?
Very well presented
Thank you Karl - please note the updated versions though.
lots of info, thanks
Cheers, Kane.
can you install nodered on a raspberry pi 2b (via app) with wifi adapter?
Hi, I followed your set up, brillient work BTW. Only problem is the node red 9 which it installed is not compatible with nbm 5.5.1
So although it’s all working I can’t add any new nodes.. I need to revert to a older version of nvm or node red ..
Being new to Linux I can’t find how to do this could you offer any advise,, thanks
Erg (thanks for this) - it was some while since I published this video and it seems that the very reason for doing it has reoccurred - ie a misalignment of all of the component packaages. When I have time I'll go back and review this. Thanks for the advice.
THIS may help you th-cam.com/video/z9a_ztJqaII/w-d-xo.html
awesome video thank you Richard. I'm hoping to add a Wemo plugin for Amazon Echo to the Pi UART
Does the Sudo npm install -g npm node-gyp take long? its been chugging at it for 45 mins now :/
yes - be patient. You can really mess things up otherwise. Let me know how you get on.
Thanks for the response
unfortunately the nodered and npm upgrade did not work for me, tryed it twice, came back with a few errors and the lost of the serial port.
this way worked for me
latest jessie install and updated as per your video. then
sudo update-nodejs-and-nodered
sudo reboot
sudo update-nodejs-and-nodered (again)
sudo reboot (again)
now fully works,
Brilliant. I love success. Let me know how you get on.
Thank you Richard. I must have done something wrong. I don't see a manage pallet in node-red to load the dashboard. I hope there is something simple I might try before I reformat my sd card and start over. These are the versions i get right now
.pi@raspberrypi:~ $ npm -v
4.0.5
pi@raspberrypi:~ $ node -v
v7.4.0
One more funny thing, when I start node-red I get this warning
Jan 17:45:19 - [warn] ------------------------------------------------------
7 Jan 17:45:19 - [warn] [serialport] Error: Module did not self-register.
7 Jan 17:45:19 - [warn] ------------------------------------------------------
That's the packet manager and node versions node red has to be Node-RED version v0.15.2. I'm sorry if that was not clear.
You people are the best. The Dashboard is now installed and running. and you are the first to ever answer a question that I have asked. Some day I hope to know enough to pay it forward. Thank you.
A lovely start to a Sunday morning. Thank you.
okay - now can YOU password protect the NodeRed front end?
Hi, how can iget data of an atlas scientific temperature sensor RTD in node red and raspberry pi 4?
Do you have details of the device?
What is , sudo npm install -g n? There was no explanation of what this is? I did it expecting it to upgrade my node version but it wasn't that.
It just adds a symbolic link for version2.
good teaching man
thanks :)
Brilliant!
Thanks.
At about 30 minutes, you install the /debian/mosquitto-wheezy.list, but you're running Jessie. Why is that? Also, I am fairly sure that link no longer works.
Yes, time goes past and things change rapidly. Everything runs Stretch now and I'd recomment using MQTT over a secure link by default too. It's a matter of time and continual development and I'm struggling with both currently.
I have a problem, lost the connection to server, can you help me?
Difficult, could you provide a full description?
Question
Why did you bother getting the python linked mosquito of Node-RED uses JS?
Sorry I don't understand this question.
Ah just worked it out - this video over ran so I cut great chunks out - forgetting about that python. Well spotted! There is one other big error - can you spot that too?
Well, just read my question and I am not surprised you didn't get it right away.
The only reason I caught the python reference is because I was looking at writing the logic for my homes MQTT broker in python before I watched your video.
I would have to watch the video again to see if I could catch your other error. I am fairly new at this no nothing stuck out.
you said left hand pane when the dashboard appeared on the right pane
and one of them was the epoch timing - it is measured in milliseconds
The Python-Mosquitto module can't be installed as it has been donated to paho-eclipse, you have to install paho-mqtt with pip instead. I'm inexperienced with linux and can't get this to work.
mmm okay - It's installed in htis videoas it was part of a longer program. Thanks for the feedback. btw I have revamped this as:- th-cam.com/video/z9a_ztJqaII/w-d-xo.html
